One way of doing this is to go to the toolbar and Click on View/Options. From the list of options check "Release Date".

This will put the release date of all your music (if known) on the top bar along with Artist, Composer etc. By Clicking and Holding on "Release Date" you can move it to left or right and place it to suit your convenience.

When you open iTunes, just Click on "Release Date" and all your tunes will be listed in date order. You can decide whether you want oldest or most recent date at the top.
